your statement of "Mods: Not many" is a great indication that you are safe.
To max out your MAF, you would be looking at some form of forced induction. If you don't have a supercharger or turbo, you're probably safe.
A CAI is not going to max a MAF out.
To tell you have to datalog your car during a full throttle run. If the MAF counts get to 1.0 or greater, than you are maxing it out. If not, you're fine.
